DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embankment method capable of obtaining a stable slope even if the slope is steep.

[0002]

2. Description of the Related Art At the time of embankment, the embankment is laid evenly and flattened for each layer, and it is sufficiently compacted to finish the entire cross section at a uniform density and is constructed so as to have a stable structure. However, it is limited by the strength characteristics specific to the embankment material used.

Therefore, conventionally, as shown in FIG.
The embankment structure is laid by laying the mesh reinforcing material 2 on the ground surface and the surface of the embankment layer 1 previously constructed, and alternately repeating the laying operation of the reinforcing material 2 for each embankment layer 1 and the construction operation of the embankment layer 1. We are developing. Thereafter, if necessary, a rectangular frame 3 is laid on the slope to reinforce the slope, and is joined to the end of the reinforcing member 2 to complete the formation.

[0004]

However, in this embankment method, after the slope is formed, a reinforcing frame 3 is formed.
Since the construction procedure for laying the slope is adopted, it is necessary to construct the slope with a stable slope in advance, and it has been extremely difficult to create an embankment having a steep slope.

[0005] For example, when a steep slope is to be formed, a holding form may be installed in front of the slope forming position. However, when the height of the embankment layer is increased, this type of form is disposed. Doing so is inefficient and poses a problem that the installation work is dangerous.

The present invention, is determined in advance a gradient of advance slope by law frame, Sheng can be easily construct a embankment structure having a slope steeper by performing embankment along which
The purpose is to provide an earthwork method .

[0009]

In order to achieve the above object,
In the embankment method of the present invention, in the embankment method of laying a mesh-like reinforcing material on the surface of the position of the embankment layer, and alternately repeat the work of embankment layer on the upper part of the embankment structure to form an embankment structure A reinforcing member laid on each of the embankment layers, a legal frame body formed in a rectangular shape, a pair of legs connected to a lower back surface of the legal frame body, and one end attached to an upper rear surface of the legal frame body. Are connected, and the other ends of a legal frame structure in which a legal frame composed of a pair of coupling members whose other ends are coupled to the leg portions are connected and integrated in a horizontal line are locked. by embankment to the back of, put the method frame structure on the embankment layer
That was placed on the slope face, and characterized in that it construct a embankment structure equal slope to Howaku gradient.

[0010]

According to the above construction, the legal frame main body can be made to stand on its own at a predetermined inclination angle between the legal frame main body and the leg, and the leg of each legal frame is locked to the reinforcing member. and keep it at that, and can compete with earth pressure embankment law frame back, also, that each legal frame is embedded in the embankment, resulting effect of the legs of the legal frame is pressed by the embankment, law frame structure Is prevented from falling forward.

Further, since the locking position of the connecting member with respect to the leg can be appropriately adjusted, the inclination angle formed between the slope frame body and the leg can be appropriately changed according to the planned slope of the slope to be applied. In addition, the same operation as described above is obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. Fig. 1 shows the structure of the legal framework used in the present invention.
Shows a legal frame 10. The legal frame 10 includes a legal frame body 12 in which a structural steel such as an equilateral angle steel is formed into a rectangular frame shape by welding, and a hinge portion 1 on the lower back surface of the legal frame body 12.
And a pair of legs 16 rotatably connected via the first frame 4 and one end rotatably connected to the upper back surface of the legal frame main body 12 via a hinge 18. A pair of angle adjusting arms 20, which are connecting members that are connected to each other so as to adjust the locking position, and a connecting member 22 that integrally connects the rear ends of the legs 16 to each other. Legs 16,
The angle adjusting arm 20 and the connecting member 22 are formed of a structural steel such as an equilateral angle steel or a channel steel.

A plurality of mounting holes 16a are opened in the side surface of the leg 16 along the longitudinal direction, and the angle adjusting arm 20 is locked to any one of the mounting holes 16a via bolts 24. As a result, the slope frame body 12 is fixed in a state of being inclined at a predetermined angle with respect to the leg portion 16, and a slope of a slope described later is determined by the inclination angle.

The rear end of the leg 16 has a connecting hole 16b.
Are opened, and connection holes 16b, 1 between adjacent legal frames 10 are opened.
6b are connected by bolts 26 and nuts 27 in a state where they are aligned with each other, so that the legal frames 10 are connected in a horizontal line to form a legal frame structure.
Can be configured .

FIG. 2 shows a legal frame 10 having the above configuration .
This shows an embankment method using a method frame structure . First, a mesh reinforcing material 30 is laid on the surface to be the embankment layer 28. As the reinforcing material 30, a perforated sheet of polyethylene or polypropylene, which is a so-called geogrid or polymer grid, formed uniaxially or biaxially and formed into a net shape is used.

Next, the legal frames 10 are arranged as a legal frame structure in a horizontal line in a state where the legal frames 10 are connected to each other at a position to be the slope of the embankment layer 28. The angle of inclination of each law frame body 12 is made uniform by keeping the angle adjustment arm 20 fixed to the leg 16 at a fixed position, and this becomes the slope of the slope of the embankment layer 28. Further, each leg 16 disposed above the reinforcing member 30 is locked on the reinforcing member 30 by clips 32 made of a plurality of wires or the like.

Next, soil is scattered on the back of the legal frame body 12,
The embankment layer 28 having a thickness corresponding to the height of the corresponding legal frame structure is formed by compaction and compaction. At this time, each legal frame body 1
Even if earth pressure is applied to the back of the leg 2, the leg 16 is locked by the reinforcing member 30 and the leg 16 is pressed against the bottom surface of the embankment layer 28 by the earth pressure, so that the front frame structure does not fall over. This is prevented beforehand, and is maintained at the original inclination angle.

Next, a reinforcing member 30 is laid on the surface of the corresponding embankment layer 28 by the same operation procedure, and the legal frame main body 12 is continuously overlapped with the upper part of the legal frame main body 12 already placed. By arranging 10 in a horizontal line, the legal framework
When the structure is formed, and the embankment is fixed on the reinforcing material 30 and then the embankment is formed, the embankment layer 28 is similarly formed. In this manner, the embankment formation is completed by repeating the installation of the reinforcing member 30, the fixing of the frame structure , and the embankment work to a predetermined height.

In the above-described embodiment, the inclination of the legal frame body 12 is fixed. However, for example, by gradually changing the angle between the legal frame body 12 and the leg 16 of the legal frame 10 stacked in the vertical direction, The slope of the surface can be varied. In addition, the end of the reinforcing member 30 is arranged on the back surface of the legal frame main body 12 so that the reinforcing member 30 does not protrude to the surface of the slope, so that the aesthetic appearance is not impaired. The main bodies 12 can be joined together to further enhance the restraint effect on the slope.

Further, in this embodiment, the leg is rotatably attached to the legal frame main body, and one end of a coupling member connecting the legal frame main body and the leg is pivoted to the back of the legal frame main body. capable coupled, by law frame 10 having a configuration other end is connected so as to allow adjusting the locking position relative to the legs
Although the law frame structure has been described, the inclination angle formed between the law frame body and the leg is set in advance, and the law frame body and the leg, the connecting member, the law frame body, and the leg are joined and fixed by welding or the like. Needless to say, a configuration may be adopted.

In addition, in this embodiment, the legal frame 10 is formed by using structural steel, but it may be formed by using other members such as concrete members and FRP molded products. .

[0022]

As described in detail in the above embodiments, in the embankment method according to the present invention, it is possible to adjust the inclination angle between the slope frame body and the leg in accordance with a desired slope of the slope. it can.

In addition, by locking the leg of each law frame to the reinforcing member, the earth pressure of the embankment on the back of the law frame can be borne by the connecting member.

Furthermore, the leg by the leg portions of the law frame is embedded in the sediment is held down by the embankment, Law frame structure
Since the building is prevented from falling forward, the embankment can be formed with a steep slope that is higher than the stable slope without using the holding formwork, and the workability is also improved. Therefore, the present invention is particularly suitable as an embankment method for creating an embankment having a steep slope and a stable slope.
